VEHICLE-WHEEL RIM.

` of being mounted upon a wheel elly or fixed rim and firmly secured thereto and of being quickly removed from the wheel and rei placed by a duplicate rim carrying another tire. TheA specic improvement shown is particularly applicable to the securing of rims upon wire wheels.

Other objects of my invention will appear from the following description thereof.

In the accompanying drawings which form a part of this specification/Figure 1 is a side elevation of a portion of a -Wire wheelvshowing my impro'ved'l/rim .applied rim on the line'lllfl of Fig. 1; Fig. 3 is a transvrse section through the tire and r *movable rim, removed from the fixed rim,

the position of the section being indicated by the line llllll of Fig. l; Fig. t is a transverse section through the fixed rim with the tire and tire-carrying rim removed, and. showing one of the attaching screws withn drawn to inoperative position; and Fig. is a plan view'of a portion oit' the tire-carrying .rim showing the split detachable flange removed from its seat and the lockn ingclamp also removed.

eferring to the drawings in detail, the numeral 1 designates the fixed rim of a vehicle wheel` provided with wire spokes 2. As shown ih Figs. 2 and 4, the fixed rim is the form of a rolled sheet metal channel, having flanges at each edge thereof, the flange 3 at one edge being preferably higher than the flange 4 at the other edge. These flanges are preferably bent over to form beyelcd bearing surfaces 5 and 6 for engage- Specication of Letters Patent.

ment with thle .tire-carrying rim. An angular offset is preferably rolled in the bottom of the channel, the steeper wall 7 of this offset being perforated at intervals by screwthreaded holes through which screw the screws 8 which are used to secure the tire carrying rim on the iixed rim. y

The tire-carrying rim to be used. upon this fixed rim may be of any suitable construction,provided with seats adapted to engage the beveled surfaces 5 and 6 of the thickening the metal of the rim base, so that the rim may be formed cold from flat stock. The inner surfaces of the depressed portions of the rim form inclined bearing surfaces 12 and 13, which engage the inclined bearing surfaces 5 and 6,'respectively. The wall 14 or' the depressed portion 10 of the rim, forms an abutment against which the ends of the screws 8 press, the screws 8 thus serv ing to wedge the rim in position upon the fixed rim and retain it in such position. Fig. 2- shows one of' the screws S in operative position, while Fig. l shows the screw withdrawn. It will be seen that, owing to the inclination of the screws, by unscrewing them a few turns into the position shown in 4, the ends of the screws will be withdrawn below the level of the supporting surfaces of the fixed rim, and thus permit the tire-carrying rim to be removed from the wheel. The screws 8 are preferably given a comparativelyl steep inclination `so that they will not have to be withdrawn very far before clearing the rim. if this inclination is sui'icientlygreat, particularly if the inclination of the screws is greater than that of the bearing surfaces 4of the fixed rim or telly band, the screws will. not only torce andA 11 yrolled therein, preferably. without the rim laterally upon the .vheel, thus causing the inclined surfaces 12 and 13 to wedge upon the inclined surfaces and 6. but the screws may also tend to liftjthc rim slightly, 5 thus forcing' it away from the surliates 5 and 6. Such action is in no vvay objectionable, but rather advantageous, as the lifting of the rim opposite the screws will cause it to be dravvn into tight cls nnping contact 19 with the surfaces 5 and G throughout the space between adjacent screws. A very secure mounting of the rim upon the vehicle Wheel is thus rbtaincd.

It will be seen that the heads of the screws are very conveniently positioned, and that the screws may be operated by a brace wrench, such asis commonly used for op erating demoilntable rims. The formation oi' the folly band or fixed rim with the cir*- cumferential angular offset provides a construction very easy to manufacture, adding practically nothing to the cost of the wheel. lt at the same time provides excellent bearings for the screws 8 and makes a wheel of very attractive appearance..

The rim base 9 beyond the depression. 10 is formed into a flange 15 which is preferably inwardly hooked as shown, so as to engage the base 16 of a reversible endless tireretaining flange 17. The particular con# struction of this tire-retaining flange is not, however, a part of the present invention, it being claimed in my application filed July 22, 1911, Serial Number (339,953, and the rim base may be provided with an integral, or

- any other 4torn of tire-retaining flange desired. ln order to provide the rim with a flush tire-'seating surface, the depression 10 may be covered by a band 18, which is prot"- 40 erably formed of an endless strip of metal, shrunk into shallow recesses 19 formed at the sides of the depression 10 to receive the edges of the band.

As above stated, the rim is preferably pro vided with a removable tire-retaining flange, this flange in the form of my invention'illuFn trated being transversely split at the point 20. Y This flange, which is designated by the numeral 21, is provided with a base Z2 which is received in a chan-nel in the rim. This channel is preferably formed by carrying the rim base beyond the depressionv 11 to provide a cylindrical seat 23 and a vertical retaining flange Q4. ln order to cover the depression 11 and provide a smooth seating surface for the tire, a band is used, this band having` a vertical leg Q6 1which seats in a recess 27 formed by offsetting the rim base, the side of this vertical leg 26 completing the 5o channel for the reception of the base 22 of the flange 21. The band 25 is preferably shrunk into position in the same way as the band 18, the edge of the cylindrical portion of the band being received in the shallow re i cess 28.

T he flange 21 is reversible and may be of practically the same construction as the split tire-retaining flange shown in the pati ent to Bryant above referred to l prefer, however, to form in that side ot the flange 7@ designed to engagea straight-sided tire, an annular groove l have .found that the formation of such a groove in this `face of the flange in no Way interferes vvith the satisfactory retaining of a straight-sided tire, y@ 1a'hile the amount of metal removed by the formation of such a groove is sufficient to re salt in a material reduction in 'Weight of the rim.

The flange 21 is provided at its ends vvith 8g lugs '80 which project through a slot 31 cut in the channel portion of the rim, such slot being clearly illustrated in Fig. 5.- It preferably has one end Wall, 32, formedatright angles to the edge of the rim, the other end. S5 Wall 83 beingr inclined or beveled. ln applying the flange to the rim, one ot' the lugs 30 is placed against the Wall and the base 22 of the flange pressed into the channel, the beveled wall 33 serving to guide the lug 30 90 at the opposite end of `the flange into position, and to draw the ends of the flange to- Ward each other. A small lug Sel is preferably provided on a line with the bottom ofA the channel, to engage the first lugBO and prevent `the same from slipping away from the Wall 32 of the slot.

l? or securing the lugs 30 together and to the rim, and thus holding the split tirere taining flange in position upon the rim, prefer to use the improved locking clamp i shown in Figs. 1, 3 and 5, described and claimed in my co-pending application .Serial Number 692,256, filed April 522, 1912.

It will be seen from the foregoing descrip- 195 tion of my invention that I have provided a rim structure in which the tire-carrying rim may be detachably but firmly secnred upon the fixed rimr of a Wheel, the securing means permitting of the ready removal and re- 11o placement of the rim.

llVhile I have shown in the drawings and specifically' described a certain preferred embodiment of my invention, it is to be understood that do not intend to limit myself to the details illustrated, but that my invention is capable of modification andof being embodied in other structures.
